5) we are asked to express 625 x343 x81 into power notation

${25}^{2} \times {7}^{3} \times {9}^{2}$

6)To find the number that divides 8788 so that we obtain the quotient as a perfect cube,

Find the multiples of the number 8788,

8788 = “2 x 2 x 13 x 13 x 13”

8788 = 4 x 13 x 13 x 13

$8788 \div 4 = 13 \times 13 \times 13$

$2197 = {13}^{3}$

Hence the number 8788 must be divided by 4 so that the quotient is a perfect cube
