Question

Find m in 5 is to the power 2m divided by 5 is to the power 3 is equal to 1/5 is to the power -1

Answer 1

Answer:

Equation of this question will be

$(5)^{2m} \div {5}^{3} = {(1 \div 5)}^{ - 1}$

=>

${5}^{2m} = 5 \times {5}^{3}$

=>

${5}^{2m} = {5}^{4}$

So ,on comparing LHS and RHS ,we get

2m=4

=> m=2
