Answer 1

Answer:

$\frac{7}{4} ^{10}$ OR x=10

PLEASE MARK ME AS BRAINLIEST...

Answer 2

Step-by-step explanation:

(7\4 )³ x (7\4)⁵ (we know if any rational is multiply then result will be (+) .For example (a\b)³ x (a\b)⁵ is (a\b)³ + ⁵ is (a\b)⁸

Similarly (7\4)³ + 5 is (7\4)⁸

Now (7\4)⁸ = (7\4)^x - 2 ( 7\4 is common so we will cut it and write the powers of equation)

Now equation is 8 = x - 2

=) 8 + 2 = x

Ans = 1O

Plz mark me branliest ...it take me too much time to write it
