Sin means to divide the opposite side measure by the hypotenuse. Cos is equal to the adjacent side value divided by the hypotenuse. Tan is equal to the opposite value divided by the adjacent. To remember this, I use the abbreviation SOHCAHTOA. SOH for Sin is Opposite over Hypotenuse, and so on.
Assuming you want to solve for a, then
ad - 7 = y (reversing the equation to have a on left side )
add 7 to both sides to isolate the term with a
ad = y + 7 ( divide both sides by d )
a = 
1) what law of exponent is being described in the given ?
y⁴ x y⁷ = y¹¹
<h3>Answer :- Product of Powers ✓ </h3>
- When numbers with the same base are multiplied, the power of the product is equal to the sum of the powers of the numbers.
- If 'a' is a non-zero integer, and 'm' and 'n' are whole numbers then, am × an = am+n.

2) what law of exponent is being described in the given ?
(m⁵n³)² = m²x^²n³x^²
<h3>Answer :- Power of a product ✓ </h3>
- We use the power of a product rule when there are more than one variables being multiplied together and raised to a power.
- The power of a product rule tells us that we can simplify a power of a power by multiplying the exponents and keeping the same base.
