When we multiply exponents with the same base we add the exponents

When we divide exponents with the same base we subtract the exponents

4^3 * 4^3 ÷4^3 *4^3

We will work from left to right

Multiply means add

4^(3+3) ÷4^3 *4^3

4^6÷4^3 *4^3

Now divide means subtract

4^6÷4^3*4^3

4^(6-3)*4^3

4^3 *4^3

4^3*4^3

Multiply means add

4^(3+3)

4^6

4^6 = 4^x

The bases are the same so the exponents must be the same

x=6

What is the distributive property of 0.4(0.3m+0.6n

svlad2 [7]

Answer:

Distributive property for the given expression is

$0.4(0.3m+0.6n)=0.12m+0.24n$

Step-by-step explanation:

Distributive property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

$A(B+C)=A\times B + A\times C$

For example 2(x+y)=2x+2y

Therefore,

$0.4(0.3m+0.6n)=0.4\times 0.3m+0.4\times 0.6n=0.12m+0.24n$

Therefore,

$0.4(0.3m+0.6n)=0.12m+0.24n$
