What is the product of -4 and 8.1? a) -32.4 b) -12.1 c)12.1 b) 32.4

Sergeeva-Olga [200]

Option A

Answer:

The product of -4 and 8.1 is -32.4

Solution:

When we multiply a negative number with a positive number we get the resultant product as a negative number.

Here we have to multiply - 4 which is a negative number and 8.1 which is a positive number.

To simplify the multiplication calculation we can write 8.1 as 8+0.1 and then multiply 4 with both 8 and 0.1

-4 $\times$ 8.1 = -4 $\times$ (8+0.1)

⇒ -4 $\times$ 8.1 = -4 $\times$ 8 – 4 $\times$ 0.1 [Multiplying 4 with 8 and 0.1]

⇒ -4 $\times$ 8.1= -32 - 0.4

⇒ -4 $\times$ 8.1= - 32.4

Thus the product of -4 and 8.1 is -32.4

3+(2+8)2ndpower ÷4×(1/2) 4th power

PIT_PIT [208]

Answer:

412

Step-by-step explanation:

You have to follow PEMDAS and solve the problem carefully.

$\frac{3+(2+8)^{2} }{4*(\frac{1}{2} )^{2} } =\frac{3+(10)^{2} }{4*(\frac{1}{2} )^{2} } = \frac{3+100}{4*(\frac{1}{2} )^{2} } = \frac{103 }{4*(\frac{1}{2} )^{2} }$

$\frac{103 }{4*(\frac{1}{2} )^{2} } = \frac{103 }{4*(\frac{1}{16})} } = \frac{103 }{\frac{1}{4} } =\\103*4\\=412$
