What is the following product?<br> 4V7•4V7•4V7•4V7<br> A 4(4V7)<br> B 4v7<br> C 7^4<br> D 7

Answer:

Option (4)

Step-by-step explanation:

Let x = $\sqrt[4]{7}$

$\sqrt[4]{7}\times \sqrt[4]{7}\times \sqrt[4]{7}\times \sqrt[4]{7}$ = (x)(x)(x)(x)

= $x^{1+1+1+1}$

= x⁴

Now we substitute the value x = $\sqrt[4]{7}$

x⁴ = $(\sqrt[4]{7})^4$

x⁴ = 7

Therefore, Option (4) will be the answer.

The sum of interior angles in a triangle are 180 degrees. Angle B and C are congruent. Angle B is twenty less than angle A. Writ

Margarita [4]

Answer:

A = 73.33

B = 53.33

C = 53.33

Step-by-step explanation:

Mathematically, adding the 3 angles would equal 180

Thus;

A + B + C = 180 •••••(i)

Since B and C are congruent, that means they are equal ( we are looking at isosceles triangle)

B = C •••••••••(ii)

Lastly;

B = A -20 ••••••••(iii)

Make a substitution in equation 1;

A + A -20 + A -20 = 180

Since B = C ; C also is A-20

3A -40 = 180

3A = 220

A = 220/3 = 73.33

B = C = A -20 = 73.33 -20 = 53.33
