One way it's useful is in the application of phasors in physics. Phasors require you to add up vectors of two different angles, so the cosine angle addition formula can be used if you already know the cosine and sine of the original vector angles.

The equivalent expression to 11^-7 × 11^5 is one over eleven raised to the second power. option A
Exponential
11^-7 × 11^5
= 11^(-7+5)
= 11^(-2)
= 1 / 11²
Options:
one over eleven raised to the second power
(1/11)²
one over eleven raised to the power of negative two
(1/11)^-2
11^2
−11^2
Therefore, the equivalent expression to 11^-7 × 11^5 is one over eleven raised to the second power.

Pythagorean Theorem: a^2 + b^2 = c^2
(5)^2 + (9)^2 = c^2
25 + 81 = c^2
106 = c^2
c = square root of 106
Length of a diagonal of a rectangle is square root of 106.
