1.1 and -1.1\nbut you don't need to round it, that is the exact answer.

0.7 * 10^2 or 0.7 E+2 in some calculators,\n\nmeans that you must take your decimal (0.7 in this case) and shift the point a number of times as the exponent says (in this case 2) to the right if it is positive (like in this case) and to the left if it's negative.\n\nIn this case you must move the point two steps right: \nfrom 0.7 to 7.0 (first step) and then to 70. (final answer)\n\nAnother couple of exemples:\n\n.35 E-6 (or 0.35 * 10^-6)\nyou must move the point six steps left:\n0.00000035\n\n0.445 E+10 (or 0.445 * 10^10) \nyou must move the point 10 steps right:\n4450000000.

do you mean 18 times the sq rt of 50, that would be 127.3\nthen subtract 21 times sq rt 40 divided by 3 times sq rt 2\nOr, is all of the subtraction part above the line\nSee if you can rewrite the problem

The answer is:  4.47, and that's all there is to it!\n\nOk Vanessa, all you have to do is pull up your calculator (Start>Accessories).\nI am not suggesting you don't work it out in your head first: it's just basic. Check the answer on the calc, or, if you get stuck....go back.... to POWERS OF HIGH HOLY ROOTISM   SQUARE YOU KNOW, 1x1+(2x2)+2+(10-5)/1=       Simple:\n1+4+2+5/1=12

just divide both sides by 0.015...\n\nand you will get...\n\n566.66 \n\nwith a repeating six.

Use a calculator and raise it to the 1/3 power.\nDon't try to do it by hand...

I assume you mean a sq rt of a third.\n\nsqrt( 1/3) = 0.5774

Yiu would first decide how many decimal places you are going to consider.  The usual is 3.  Then work it from there...;

Just move the decimal place two spaces to the left ;)\n\n325. % = 3.25\n\n0.056 % = 0.00056
