What are the last 2 digits of 7 to the power of 2018. This question was on a past exam paper.
Xelga [282]

Answer:

49

Step-by-step explanation:

  • Try finding pattern of last two digits of 7 to the power of some numbers.

7^1=07

7^2=49

7^3=343

7^4= 2301

7^5= 16807

  • so , the pattern is, 07,49,43,01
  • so, if we start writing all numbers from 1 to 2018 , four number in each line, 2018 will fall in the second column.
  • so it will have 49 as the  last 2 digits [by seeing this pattern : 07,49,43,01 ]

Solve for p: -9 + p &lt; 15 <br> A. p &gt; 24 B. -p &gt; 6 C. p &lt; 24 D. -p &lt; -6
Soloha48 [4]

Answer:

C.  In the given expression -9 + p < 15 , the value of p <  24.

Step-by-step explanation:

Here, the given expression is :

-9 + p < 15

Now, solving for the value of p.

If equals are added to both sides of inequality, the inequality remains unchanged.

Now, -9 + p < 15

⇒  -9 + p  + 9 < 15  + 9                                  (adding +9 on both sides)

or,  p <  24

Hence, in the given expression -9 + p < 15  the value of  p <  24.
