Question

Find the value of m for which 9m +3^-2= 9^4​

Answer 1

Step-by-step explanation:

9m+3^-2 =9^4

9m+1/9=6561

9m=6561×9

9m=59049

9m=59048

m =6561

This may help you

Answer 2

Answer is 729

9m +3^-2 =9⁴

9m +1/3² =9⁴

9m + 1/9 =9⁴

81m + 1/9 = 9⁴

81m + 1 = 9⁴ ×9

81m+1 = 9^5

81m+1 =59049

81m +1=59049

81m=59049-1

81m= 59048

m= 59048÷81

m=729
