Answer 1

Answer:

I have solved all the three questions

I hope it will help you

Answer 2

Step-by-step explanation:

(i) 5^2n x 5^ 3 = 5^9

in multiplication, if base are same than powers are added,

therefore,. 5^2n+3 = 5^9

2n + 3 = 9

n. =. 9 - 3 ÷ 2

n = 3

(ii) 8 x 2^n+2 = 32

simplify......

2^3 x 2^n+2 = 2^5

in multiplication, if base are same than powers are added,

n+ 2+ 3 = 5

n = 0

(iii) 6^2n+1 ÷ 36 = 6^3

simplify.......

6^2n+1 ÷ 6^2 = 6^3

in division, if base are same than powers are subtracted,

2n + 1 - 2 = 3

2n - 1 = 3

n = 4 / 2

n= 2
