Rewrite the following without an exponent. 6^-2<br> Please answer ASAP!

julia-pushkina [17]

Answer:

Rewriting $6^{-2}$ without an exponent we get $\mathbf{\frac{1}{36}}$

Step-by-step explanation:

We need to rewrite the following without an exponent. $6^{-2}$

We need to solve the exponent to find the result.

We know the exponent rule: $a^{-b}=\frac{1}{a^b}$

Now using this rule to solve the equation:

$6^{-2}\\=\frac{1}{6^2}\\We \:know \:that\:6^2 = 6\times 6=36\\=\frac{1}{36}$

So, Rewriting $6^{-2}$ without an exponent we get $\mathbf{\frac{1}{36}}$

Please help find the value of t?

Gwar [14]

Step-by-step explanation:

volume=8448m²

volume=l×b×h

=11m×8m×t

=88m²×t

therefore, 88m²×t=8448m²

t= 8448/88

= 96

Check:-

volume= l×b×h

=11m×8m×96

=8448m³

Our answer is correct

Complete y^2+15y+56=(y+7)(y+?) ...?

Rufina [12.5K]

The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:
y² + 15y + 56 = (y + 7)(y + a)
y² + 15y + 56 = y² + (7 + a)y + 7a
We can now compare the coefficient of the like terms, either the one with y or the one without y, and find the value of a.
15 = 7 + a; a = 8
OR
56 = 7a; a = 8

Second factor is (y + 8)
