Answer: pi(3)^2
I was just on the quiz and got it correct
The answer is going to be A.) -2
The second one:
3^7 x 3^(86/10) x 3^(9/1000)
That is because when you multiply powers with the same base ( in this case they are all 3), you just leave the base as it is and add the exponents
so it is basically 3^(7 + 86/100 + 9/1000) which is 3^7.869
ΔIJK ≈ ΔPQR => ∡I = ∡P =>
=> 3X + 4 = 72 - X
3X + X = 72 - 4
4X = 68
X = 68 : 4
X = 17
