What is the fifth term in the binomial expansion of (x + 5)8?

Step-by-step explanation:

Given:

It is binomial expansion. It has two term with power 8.

Formula:

If then

This is general formula of the expansion.

For fifth term, T₅

So, r=4

Put r=4 and n=8, a=x, b=5 into formula and we get

Hence, The fifth term of the given binomial is 43750x⁴

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

4th option is correct xy=-10
