Answer:

Step-by-step explanation:

When an expression is evaluated, the expression is either simplified or calculated.

The result of the expression is 47

The expression is given as:

Where:

x = 2 and y = 4

Substitute 2 for x and 4 for y in the expression

So, we have:

Evaluate all exponents

Evaluate all products

Evaluate like terms

Hence, the result of the expression is 47

Prove algebraically that (m + 2)2 – m 2 – 12 is always a multiple of 4

Julli [10]

Answer:

$(m + 2)^{2} - m^{2} - 12 = 4(m - 2)$

Step-by-step explanation:

Step 1:

Write the expression

$(m+2)^{2} - m^{2} - 12$

Step 2: Expand $(m + 2)^{2}$

$(m+2)^{2} - m^{2} - 12\\(m+2)(m+2) - m^{2} - 12\\m^{2} + 2m + 2m + 4 - m^{2} - 12$

Step 3: Collect similar terms

$m^{2} - m^{2} + 4m + 4 - 12\\4m - 8$

Step 4: Factor 4 out of the expression to prove that the expression is a multiple of 4.

$Therefore\\4m - 8 = 4(m - 2)\\Hence,\\(m+2)^{2} - m^{2} - 12 is a multiply of 4 because the expression is equal to 4(m-2)$

Can you please help me with this

Vitek1552 [10]

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log( $\frac{x}{y}$ )

log $x^{n}$ ⇔ nlogx

Given

2(log18- log3) + $\frac{1}{2}$ log $\frac{1}{16}$

= 2(log( $\frac{18}{3}$ ) ) + log $(\frac{1}{16}) ^{\frac{1}{2} }$

= 2log6 + log $\frac{1}{4}$

= log6² + log $\frac{1}{4}$

= log36 + log $\frac{1}{4}$

= log( 36 × $\frac{1}{4}$ )

= log9
