Question

Work out 5^-2 x cube root of 8

Answer in decimal form please.

Answer 1

0.08

Explanation:

When you multiply a number by a negative exponent you put the number over 1 and make the exponent positive.

`5^(-2)`------->
`(1)/(5^(2) )` -------->
`(1)/(25)`

To convert into a decimal:

`(1)/(25)`=
`(x)/(100)`

x=4

Then for the cube root of 8

3
`√(8)`=2

0.04*2=0.08
