A x 60 = b. work out the value of 4b/a. Also

Write 27 x (3, squared) power of 7 as a single power of 3

Thanks

a) 240

b) 3¹⁷

Step-by-step explanation:

Given the expression a * 60 = b   1

We are to find 4b/a 2

Substitute equation 1 into 2;

f(a, b) = 4b/a

f(a, b) = 4(60a)/a

f(a, b) = 240a/a

f(a, b) = 240

hence 4b/a is 240

b) Given the expression 27 *(3²)⁷

This can also be written as;

27 *(3²)⁷ = 3³ *(3²)⁷

3³ *(3²)⁷ =  3³ *3¹⁴

3³ *3¹⁴ = 3³⁺¹⁴

3³ *3¹⁴ = 3¹⁷

Hence the value in power of 3 is 3¹⁷

a - base

b - exponent

so,

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
