64y^18 -1000z^6 = (4y^6)^3 -(10z^2)^3
Tcecarenko [31]2 years ago

Answer:

64y^{18} - 1000z^{6} = (4y^{6} )^3 - (10z^2)^3 =  (4y^6 - 10z^2) (16y^{12} + 40y^6z^2 +100z^4)

Step-by-step explanation:

The given expression is 64y^{18} -1000z^{6}

Here we can rewrite the given expression.

64 can be written as 4*4*4 = 4^{3}

y^{18} =( y^{6}) ^3 using the power of power rule of exponent.

So. 64y^{18} = (4y^6)^{3}

Now we can write 1000z^{6} = (10z^2)^3

Therefore, 64y^{18} - 1000z^{6} = (4y^{6} )^3 - (10z^2)^3

This can be written as using the formula (a - b)^3 = (a - b)(a^2 + ab + b^2)

Here a = 4y^6 and b = 10z^2

= (4y^6 - 10z^2) (16y^{12} + 40y^6z^2 +100z^4)

Given loga (m) = 10 and loga (n) = 25 , find loga (m * n ^ 2)
mina [271]

The result of the log function log_a (m * n ^ 2)  is 60

According to the law of logarithm if log_ab=y then b=a^y

Given the following expressions

log_am=10\\log_an=25

This can be expressed as

m =a^{10} \ and \ n = a^{25}

Substitute the value of m and n into the expression log_a (m * n ^ 2) to have:

log_a (m * n ^ 2) = log_a(a^{10}\times a^{50})\\=log_aa^{60}\\=60log_aa\\=60(1) \\= 60

This shows that the result of the log function log_a (m * n ^ 2)  is 60

The length of a rectangle is 5 more than twice the width. If the perimeter of the
Rzqust [24]

Answer:

The dimensions of the rectangle are two unknowns: The length "l" and the width "w"

The perimeter of a rectangle is found as P = 2*l + 2*w

We also know that the length is 5cm more than twice the width. l = 2*w + 5

These two equations gives us a system of linear equations.

P = 2*l + 2*w

l = 2*w + 5

We can use substitution to replace the "l" in the first equation with 2*w + 5

P = 2*(2*w + 5) + 2*w

P = 4*w + 10 + 2*w

P = 6*w + 10

We know that P = 34cm

34 = 6*w + 10

Subtract 10 from both sides

24 = 6 * w

Divide both sides by 6

4 = w

Now that we know the width, we can find the length by substituting 4 for "w" in the second equation.

l = 2*4 + 5

l = 8 + 5

l = 13

The dimensions of the rectangle is 13cm x 4cm
