Step-by-step explanation:

To write the equation in LaTeX in form y = ab^x  or ab^x for y = abx .........(1)

(a) LaTeX: y=3\sqrt{4^{2x}}  y = 3 4 2 x can be written in mathematical form as

y=3\sqrt{4^{2x}} ; y = 342x

on comparing with equation (1) we get a =3 and b =4

⇒y = 34^x or 34^x

(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as

y=\frac{\sqrt[3]{5^{3x}}}{2} ; y = 342x

on comparing with equation (1) we get a =0.5 and b =5

⇒y = \frac{1}{2}5^x

(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as

y=8^{x+2}

on comparing with equation (1) we get a =64 and b =8

y = 64 . 8^x

(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}  can be written in mathematical form as

y=\frac{3^{2x+1}}{\sqrt{3^{2x}}} = 3^{x+1} = 3 . 3^x

on comparing with equation (1) we get a =3 and b =3

y = 3 . 3^x

How do you simplify 3 1/4 x 3/5 someone please help me
kifflom [539]

Answer:

We want to simplify:

(3 + 1/4)*(3/5)

The first step is to write the first term as a single rational number.

We know that:

3*1 = 3

and 4/4 = 1

then:

3*1 = 3*(4/4) = (3*4)/4 = 12/4

We do this because we want to have the same denominator in both numbers, so we can directly add them.

Then we get:

(3 + 1/4)*(3/5) = (12/4 + 1/4)*(3/5) = (13/4)*(3/5)

And remember that in the multiplication of rational numbers the numerator are multiplied together and the same for the denominators, then we get:

(13/4)*(3/5) =  (13*3)/(4*5)

If we solve the multiplications we get:

(13*3)/(4*5) = (39/20)

Now, we can notice that in the numerator we have two prime numbers, 13 and 3.

And in the denominators, we have a 4 (which is equal to 2*2) and a 5.

So the prime numbers in the numerator and the denominator are all different, this means that we can not simplify it furthermore.

Then we have:

(3 + 1/4)*(3/5) = (39/20)

Simplify 4 to the 11th power over 4 to the -8th power
madam [21]

Answer:

274878070200

Step-by-step explanation:

4 to the power 11 = 4194304

4 to the power -8 = 0.00001525878

4194304/0.00001525878 = 274878070200
