Please help I need all 4 questions xx

a) 4¹²

b) 6⁷

c) 8⁵

d) 7²

Step-by-step explanation:

when multiplying numbers to the power of whatever it is, you simply add the powers. thats the most basic explanation for this. dividing powers means subtracting the powers.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
