Question. 34
The two digit number whose ten’s digit is ‘t’ and units’s digit is ‘u’ is _________.
Answer:
The two digit number whose ten’s digit is ‘t’ and units’s digit is ‘u’ is 10t + u.
Detailed Answer with Explanation:
- The number has two digits: tens digit = t, units (ones) digit = u.
- Value of the tens digit:
\( t \text{ tens} = t \times 10 \)
- Value of the units digit:
\( u \text{ ones} = u \times 1 \)
- Add both values to get the whole number:
\( (t \times 10) + (u \times 1) \)
- Simplify:
\( 10t + u \)
Quick check with an example:
If \( t = 3 \) and \( u = 7 \):
\( 10 \times 3 + 7 = 30 + 7 = 37 \)
So, the two-digit number is \( 10t + u \).
