Question

3^x+3^x3^x=729 find the x

Answer 1

Heya ✋

Let see your answer !!!!

$3 ^{x} + 3 ^{x} + 3 ^{x} = 729 \\ = > 3 \times 3 ^{x} = 729 \\ = > 3 ^{x} = 729 \div 3 \\ = > 3 ^{x} = 243 \\ = > 3 ^{x} = 243 \\ = > 3 ^{x} = 3 ^{5} \\ since \: bases \: are \: same \\ = > 3 ^{x} = 3 ^{5} \\ = > x = 5$



Thanks :)))))

Answer 2

Answer:

(x)² =25

Step-by-step explanation:

→ 3(1x+1x+1x)=729

→ 3×3x =729

→ 3x =729/3

→ 3x = 243 {we can write this as (3)⁵}

→ 3x = 3⁵

→ Bases are same on both sides

A/q

x = 5

(x)²=25
