Step-by-step explanation:

We have to rewrite the radical expression as an expression with a rational exponent.

(i) The fourth root of seven to the fifth power.

Radical expression is

Exponential form is

(ii) Seven to the five fourths power.

Radical expression is

Exponential form is

(iii) Seven to the four fifths power.

Radical expression is

Exponential form is (Answer)

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
