What is the value of expression of -5 square -3

-0.008

Step-by-step explanation:

Hi there,

When you have a negative exponent, it tells us how many times to multiply the reciprocal of the base. For example, this problem tells us to multiply the reciprocal of -5 (which is -) three times since the exponent is -3. As a final solution, you should get -0.008.

Hope this explanation helps. Cheers.  

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

step-by-step explanation:

the true ones are a b and d
