Mathematics
1 answer:
ioda3 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

∠1 and 170° form a straight angle and are supplementary, thus

∠1 = 180° - 170° = 10°

∠1 and ∠3 are vertical angles and congruent , thus

∠3 = 10°

∠2, 15° and ∠3 form a straight angle and sum to 180°, thus

∠2 = 180° - 15° - 10° = 155°

Thus

∠1 = 10°, ∠2 = 155°, ∠3 = 10°

Use the properties of exponents to rewrite the expression.<br> (-3yz)(-3yz)(-3yz)(-3yz)
Lera25 [3.4K]

Answer:

Answer is 81y^4z^4

Step-by-step explanation:

The expression is (-3yz) (-3yz) (-3yz) (-3yz).

Since all the four terms have power 1:

(-3yz)^1 (-3yz)^1 (-3yz)^1 (-3yz)^1

We know that we can add the powers if the terms have same base

So,

=(-3yz)^1+1+1+1

=(-3yz)^4

=(-3)^4(y)^4(z)^4.

If the power is an even number than the negative sign changes into positive sign.

=3^4y^4z^4

=81y^4z^4

Thus the answer is 81y^4z^4....
