Show that 155 can be expressed as the sum of a power of 2 and a cube number?

we are given

a number as 155

155 can be expressed as the sum of a power of 2 and a cube number

we can solve it by using trial and error method

Case-1:

Let's assume power to 2 is 1

so,

now, we can solve for x

it's cube root won't be a number

so, this is not possible

Case-2:

Let's assume power to 2 is 2

so,

now, we can solve for x

it's cube root won't be a number

so, this is not possible

Case-3:

Let's assume power to 2 is 3

so,

now, we can solve for x

it's cube root won't be a number

so, this is not possible

Case-4:

Let's assume power to 2 is 4

so,

now, we can solve for x

it's cube root won't be a number

so, this is not possible

Case-5:

Let's assume power to 2 is 5

so,

now, we can solve for x

it's cube root won't be a number

so, this is not possible

Case-6:

Let's assume power to 2 is 6

so,

now, we can solve for x

it's cube root won't be a number

so, this is not possible

Case-7:

Let's assume power to 2 is 7

so,

now, we can solve for x

it's cube root will  be 3

so, this is  possible

so, we can write as

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
