3² • 9³ = [ ]<br>solve ​
RideAnS [48]

Answer:

3⁸ or 6561

Step-by-step explanation:

First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

There are no parentheses, so let's solve the exponents.

3² • 9³

3² = 9

9³ = 729

Your expression is:

9 • 729

Now let's multiply.

= 6561

This number can also be expressed with exponents.

Since 9 = 3², 9³ = 3²⁽³⁾

Now your expression is:

3² • 3²⁽³⁾

First, solve the exponents by multiplying.

3² • 3⁶

When you multiply two expressions with exponents that have the same base (3), you add the exponents.

3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸

3⁸ also equals  6561.

Your answer is 3⁸ or 6561.

Hope this helps!

Help me it’s urgent
Ket [755]

Answer:

a_1 = -\dfrac{3}{4}

Step-by-step explanation:

a_1 \times r = a_2

a_1 \times r^2 = a_3

a_1 \times r^3 = a_4

...

a_1 \times r^8 = a_9

\dfrac{a_9}{a_4} = \dfrac{a_1 \times r^8}{a_1 \times r^3} = \dfrac{-196}{6}

r^5 = -32

r = -2

a_1 \times r^3 = a_4

a_1 \times (-2)^3 = 6

a_1 = \dfrac{6}{-8}

a_1 = -\dfrac{3}{4}
