4²+2²-(-3²)=m²-(-1²)+(√3)²​
nika2105 [10]

Answer:

m = ± 5

Step-by-step explanation:

Given

4² + 2² - (- 3²) = m² - (- 1²) + (\sqrt{3})² ← evaluate exponents

noting that - 3² = - 9 and - 1² = - 1

16 + 4 - (- 9) = m² - (- 1) + 3, that is

20 + 9 = m² + 1 + 3

29 = m² + 4 ( subtract 4 from both sides )

25 = m² ( take the square root of both sides )

m = ± 5

If (sin(()−1))p =2cos(()−1)q , show that p​^2​​ =4q​^2 (1− q^2) ?.
Papessa [141]
Likely the equation is

\sin^{-1}p=2\cos^{-1}q

For either side to be defined, we require |p|\le1 and |q|\le1. Under these conditions, we can take

\sin(\sin^{1}p)=\sin(2\cos^{-1}q)
\implies p=2\sin(\cos^{-1}q)\cos(\cos^{-1}q)
\implies p=2q\sin(\cos^{-1}q)
\implies p=2q\sqrt{1-q^2}
\implies p^2=4q^2(1-q^2)

as required.
