A*a*a*a*a*a*a/a*a*a*a*a*a Rewrite the expression in the form a^n

a¹

Step-by-step explanation:

The numerator (a*a*a*a*a*a*a) is a⁷ and the denominator (a*a*a*a*a*a) is a⁶ therefore the answer is a⁽⁷⁻⁶⁾ = a¹.

a

Step-by-step explanation:

a*a*a*a*a*a*a/a*a*a*a*a*a

Count the number of a's in the numerator and that is the exponent

Count the number of a's in the denominator and that is the exponent

a^7 / a^6

When we divide, we subtract the exponents

a^ (7-6)

a^1

a

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
