Question

Write the following in exponential form with full explanation.
a. -27/343
b. 1/125
c. 81/10000
d. 64/729
e. -1/1000​

Answer 1

a) -27/343

=(-3×-3×-3)/(7×7×7)

=(-3)^3 /(7)^3

=(-3/7)^3

b) 1/125

=(1×1×1)/(5×5×5)

=(1)^3 / (5)^3

=(1/5)^3

c) 81/10000

=(3×3×3×3)/(10×10×10×10)

=(3)^4 / (10)^4

=(3/10)^4

d) 64/729

=(4×4×4) / (9×9×9)

=(4)^3 / (9)^3

=(4/9)^3

e)-1/1000

try yorself..

Assume-

^2= Symbol of square

^3= Symbol of cube

^4= Symbol of to the power 4

.formulae used ;-

(a)^m / (b)^m = (a/b)^m

i hope this is useful for you.

plz mark my answer as brainliest.
