Question

pls help me solve these equations and correct will be marked brilliant :)​

Answer 1

Answer:

putx=n

10.(3³)ⁿ*3⁵*(3³)³ 3³ⁿ+⁵+⁹

__________ = _____ = 3³ⁿ+¹⁴‐¹⁷ = 3³ⁿ-³

3*(3⁴)⁴ 3¹+¹⁶

3³(3ⁿ-¹)=27=3³

3ⁿ-¹=3⁰

n-1=0

n=1.

I.e.,x=1.

2 1176

2 588

2 294

3 147

7 49

7

2³×3×7²

so,m=3;n=1;p=2

2³×18¹×5²=8×18×25=3600.

12.

(2-⁵)-⅖ ×8⁰+(-15/19)⁰

2²×1+1

4+1=5.

a)88

b)28.
