Required Answer:-
Given:
- 3x - y = 12
To Find:
- The value of 8ˣ/2ʸ
Solution:
We have,
➡ 3x - y = 12
So,
8ˣ/2ʸ
= 2³ˣ/2ʸ
We know that,
➡ aˣ/aʸ = aˣ⁻ʸ
Using this formula, we get,
= 2³ˣ⁻ʸ
Now,
➡ 3x - y = 12
➡ 2³ˣ⁻ʸ = 2¹²
➡ 2³ˣ⁻ʸ = 4096
★ Hence, the value of 2³ˣ⁻ʸ is 4096.
Answer:
- 2³ˣ⁻ʸ = 4096
More Formulae:
- a⁰ = (a ≠ 0)
- aˣ = 1/a⁻ˣ
- √a = a
- (aˣ)ʸ = aˣʸ
- aˣ × aʸ = aˣ ⁺ ʸ
