Simplify the following questions underneath.

Question

(3a^1)

b^-21

 (2x10^-3)^5

Answer 1

1st = 3a

2nd = 1/b^21

3rd = 32 x 10^-15 in scientific notation = 0.000000000000032 with 13 zeros to the right of the decimal point

= about zero when rounded to 13 or less decimal places

= 0 when simplified
